An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

A new kind of shape-shifting material can twist, bend, and snap into more than a dozen three-dimensional forms—no motors or wires required. Using stored elastic energy, it transforms itself much like ...

Energy harvesting, an eco-friendly technology, extends beyond solar and wind power in generating electricity from unused or discarded energy in daily life, including vibrations generated by passing ...

Stronger batteries, longer-lasting electric vehicles, and more energy-efficient machines could soon become a reality thanks to a breakthrough in energy storage. Several technologies rely on storing ...

Be it springs for absorbing energy, buffers for mechanical energy storage, or flexible structures in robotics or energy-efficient machines: Storage of mechanical energy is required for many ...
